Hi if your view south is clear then at 35' you should be ok.

WILW I dont know why you suggested twin lead as RG6 cable has a lower loss plus the cabe is shielded. the twin lead can pickup interference especially if he decide to run a rotor wire.

From your location from my experience I would say that you need to point your antenna more south not south west.

In relation to the cntower more east.

Dish net is west and at that position you will only get the canadian stations.

When you say fuzzy do you mean the picture freezes and pixelates ? then swing your antenna south not south west.
